What is the difference between global health and international health according to Koplan et al. (2009) in their article 'Towards a Common Definition of Global Health'?
1) Global health focuses on health issues that transcend national boundaries, while international health focuses on health issues within a specific country.
2) Global health emphasizes the importance of collaboration and cooperation among countries, while international health focuses on individual countries' health systems.
3) Global health considers social, economic, and environmental determinants of health on a global scale, while international health primarily focuses on medical interventions and healthcare delivery.
4) Global health aims to address health disparities and inequities among different populations worldwide, while international health focuses on addressing specific diseases and public health emergencies.
